template struct mrpt::maps::CLogOddsGridMap2D

Overview

A generic provider of log-odds grid-map maintainance functions.

Map cells must be type TCELL, which can be only:

• int8_t or

• int16_t

See also:

CLogOddsGridMapLUT, See derived classes for usage examples.

Typedefs

typedef TCELL cell_t

The type of cells.

Methods

void updateCell_fast_occupied(
    const unsigned x,
    const unsigned y,
    const cell_t logodd_obs,
    const cell_t thres,
    cell_t* mapArray,
    const unsigned _size_x
    )

Performs the Bayesian fusion of a new observation of a cell, without checking for grid limits nor updateInfoChangeOnly.

This method increases the “occupancy-ness” of a cell, managing possible saturation.

Parameters:

x	Cell index in X axis.
y	Cell index in Y axis.
logodd_obs	Observation of the cell, in log-odd form as transformed by p2l.
thres	This must be CELLTYPE_MIN+logodd_obs

void updateCell_fast_occupied(cell_t* theCell, const cell_t logodd_obs, const cell_t thres)

Performs the Bayesian fusion of a new observation of a cell, without checking for grid limits nor updateInfoChangeOnly.

This method increases the “occupancy-ness” of a cell, managing possible saturation.

Parameters:

theCell	The cell to modify
logodd_obs	Observation of the cell, in log-odd form as transformed by p2l.
thres	This must be CELLTYPE_MIN+logodd_obs

See also:

updateCell, updateCell_fast_free

static void updateCell_fast_free(
    const unsigned x,
    const unsigned y,
    const cell_t logodd_obs,
    const cell_t thres,
    cell_t* mapArray,
    const unsigned _size_x
    )

Performs the Bayesian fusion of a new observation of a cell, without checking for grid limits nor updateInfoChangeOnly.

This method increases the “free-ness” of a cell, managing possible saturation.

Parameters:

x	Cell index in X axis.
y	Cell index in Y axis.
logodd_obs	Observation of the cell, in log-odd form as transformed by p2l.
thres	This must be CELLTYPE_MAX-logodd_obs

See also:

updateCell_fast_occupied

static void updateCell_fast_free(cell_t* theCell, const cell_t logodd_obs, const cell_t thres)

Performs the Bayesian fusion of a new observation of a cell, without checking for grid limits nor updateInfoChangeOnly.

This method increases the “free-ness” of a cell, managing possible saturation.

Parameters:

x	Cell index in X axis.
y	Cell index in Y axis.
logodd_obs	Observation of the cell, in log-odd form as transformed by p2l.
thres	This must be CELLTYPE_MAX-logodd_obs
